Fig. 4.—Brooder (Cyphers Co.) used. These consist of a series of hot-waterpipes—heated either by means of a lamp or acoke-stove — covered with wooden hovers. Ithas been found, however, that the use of indi-vidual brooders is to be advised, as they possessmany advantages over the pipe system. In artificial rearing, a very important factortowards success is the temperature at which the hottest part of the brooder is kept. For thefirst ten days this should not be allowed to fallbelow 90° F., and if five degrees above this noharm will be done. After ten days the tem-perature should be lowered by five degrees eachweek, until the chickens areold enough to do withoutartificial heat. It is foundin practice that when a largebrooder is used to its utmostcapacity it is better to workat rather a higher tempera-ture than when a smallernumber are together. Thereason for this is that thereis always a tendency for themto crowd, and the additionalheat hinders this. All brooders for use out-of-d
